According to accident data statistics in China, the pavement skid-resistance performance influenced traffic safety greatly in expressway tunnels. Skid-resistance evaluation standard for common highway section can't be applied to tunnel pavement for the special traffic environment in tunnels. Based on drivers' expectation of pavement adhesion, traffic characteristics in tunnel and vehicle dynamics, critical braking adhesion coefficient is proposed as the unacceptable level of skid-resistance for tunnel pavement, and then safety evaluation standard of skid-resistance performance for tunnel pavement is carried out. Finally, safety measures related to pavement skid-resistance performance are discussed.
